  • Lies, Damned lies and Statistics by: Tareq Abu Saleh

    In recent years, the dental literature has notably relied on evidence rather than personal experience. Some researchers and many readers have considered statistically significant statements -whether corroborating or refuting an investigation claim- as a synonym to true or evident statement. Unfortunately, adopting this approach -Alone- is a confusing rather than an affirmative way.

    Overview of Procedures for Implant Placement at Posterior Maxilla by: Tareq Abu-Saleh and Young-Ku HEO

     

    Dental implant placement at posterior maxilla is often complicated by bone resorption, poor bone quality and the presence of pneumatized maxillary sinuses. Several techniques have been proposed to facilitate implant placement at posterior maxilla, but the need for a range of surgical interventions, the rate of complications and the extended time-consuming procedures involved, limited patient acceptance of the proposed treatment options.

     

    Novel methods were advocated for implant placement at posterior maxilla, whereby the sinus membrane can be elevated quickly and safely via lateral or crestal approaches, or short implants could be placed achieving successful outcome. The surgical time is markedly reduced and the techniques were reportedly comfortable for patients and surgeons.

     

    This review presents the scientific concepts and the level of evidence of the clinical procedures of those techniques.

    Magnification in Endodontics | A Literature Review By: Ali Abu Nemeh, Jamal Aqrabawi

    Thorough mechanical and chemical cleansing of the entire root canal system and its complete obturation with an inert filling material are one of the most important objectives of successful endodontic treatment.
     
    Recent developments in dental equipment have improved the clinician’s ability to clean, shape, and obturate almost the entire root canal system, thus increasing the quality and the efficiency of root canal treatment. The introduction of magnification devices has resulted in technical changes in the approach to root canal preparation.
     
    Along with the development of such devices, the use of magnification and well-focused illumination devices has been recommended to provide the minimum standard of care. This review of the literature presents the role and merits of magnification in endodontics.

    Immediate Implant Placement and Temporization in the Aesthetic Zone in the Presence of Horizontal and Vertical Bone Defect | A Case Report By: Meouchy Badry, Choueiry Chady, Mouchref Hamasni Fatme, Rifai Mohammad
     
    BACKGROUND: A 52-year-old male patient presented with an endodontically failed right maxillary central incisor. The patient expressed high esthetic demands: ”I can’t walk away without a tooth, and I can’t support any removable appliance”. The clinical and radiographic examination revealed according to Elian et al. (2007) a type 2 defect site requiring guided bone regeneration procedure prior to implant placement, moreover the presence of diastema contraindicated any bonded provisional prosthetic solution.
     
     
    METHODS: After tooth extraction, a localized alveolar ridge deficiency did not prevail the immediate placement of a tapered 5×13mm diameter dental implant (Full Osseotite tapered implant, Biomet 3i®, Palm Beach Garden, Florida) with bone regeneration using xenograft granules of Endobon® (Biomet 3i, Palm beach Garden, Florida). Simultaneously, a temporary platform switching abutment was screw-retained on top of the implant allowing for a four months healing period. Later, the implant demonstrated excellent conditions for impression taking and the final restoration was screw-retained 5 months following implant placement.
     
     
    DISCUSSION: The immediate implant placement is an ideal treatment option for the proper candidate. Several factors must be taken into consideration to allow clinical success and attain patient’s expectations.
     
     
    CONCLUSION: This case report describes the successful replacement and temporization of a failed maxillary central incisor with a Biomet 3i® implant after immediate placement and a bucco-lingual augmentation of the resorbed alveolar ridge.

    Management of Moderate Fluorosis: a Conservative Approach By: Rim Mabrouk, Najet Aguir Mabrouk, Hedia Ben Ghénaia, Bhouri Lotfi

    The unaesthetic appearance of the anterior teeth affected by dental fluorosis represents the chief complaint of patients and request for aesthetic treatment. This article describes a conservative technique to treat moderate cases of enamel fluorosis with micro-abrasion followed by home whitening treatment with carbamide peroxide gel.
     
    A microabrasion technique is shown to be a proven method for removing enamel discoloration defects from teeth, while dental whitening is useful for obtaining a uniform tooth shade.
     
     
    The association of these techniques presented excellent results and patients were satisfied. Both techniques are painless, fast and easy to perform, in addition to preserving the dental structure. Treatment showed immediate and permanent results.

    Effects of Light Activated Bleaching and Tetra pack Orange Juice on Micro-morphology and Composition of Dental Enamel By: Nazish Fatima, Wasif Iqbal, Mehwish Hussain

    OBJECTIVE: To study the effects of 38% Hydrogen peroxide activated with LED light and tetra pack orange juice on micro morphology and mineral content of enamel surface.
     
    MATERIALS & METHOD: A total of 45 human enamel discs were incubated in saliva overnight to allow pellicle formation and then divided into three groups: 15 for control (G1), 15 for bleaching treatment (G2), and 15 for orange juice immersions (G3). Surface micro-morphology, calcium and phosphorus were measured with Scanning electron microscope along with energy dispersive spectroscopy five day after treatment. Enamel discs of group 2 were treated with H2O2 with LED and group 3 with orange juice for 15 min each cycle repeated four times for five days to simulate daily treatment with the products for 5 days. The discs were stored in saliva between treatment cycles. Normality of the variables was checked by Shapiro-Wilk’s test and all variables were found to be approximately symmetric. Repeated measures ANOVA with post-hoc analysis was run to assess the changes in percentages of calcium and phosphorus due to different application.
     
    RESULTS: Mild alteration was seen on enamel surface of control group. The photomicrographs of enamel surface after bleaching and irradiated showed moderate generalized surface roughening. Severe alteration of enamel surface was observed in group 3.
     
    Group 3 (Orange juice) produced greater calcium and phosphate loss in comparison with all the other groups (p<0.0001). No significant difference (p>0.999) was observed in calcium and phosphorus loss between group 1 (control) and group 2 (bleached).
     
    CONCLUSION: Group 3 (Orange juice immersion) significantly altered morphology and increased loss of calcium and phosphorus erosion of enamel as compared to group 1 (control) and group 2 (Bleached) so, there was significant difference between control and immersion group. There was in significant difference between control and bleached group.
